This all sounds really cool if you can pull it off, and shared-nothing
threads do seem like the least impossible model to pull off. But "least
impossible" and "possible" are different :-). From your email I can't tell
whether this plan is viable while preserving backcompat and memory safety.

Suppose I have a queue between two subinterpreters, and on this queue I
place a list of dicts of user-defined-in-python objects, each of which
holds a reference to a user-defined-via-the-C-api object. What happens next?
